What we call protein is in reality a member of the amino acid molecules and when combined we get various combos of proteins. We need protein at all stages of our lives, for a vast variety of bodily functions. It’s the major component of all cells, including bone and muscle. It’s needed for growth, development, and immunity to fight off infections and protect your body.
The animal tissue in that steak is made up of a variety of amino acids building blocks. I highly recommend the consumption of meat not only for its great taste but also for its effect of your blood sugar management, caloric efficiency and human biology. For those seeking the vegetarian option of dieting keep in mind that it takes more calories to get proper amount of carbs into ones diet.
Protein can be found a a variety of foods such as:

Grass feed cows is the best way to go as cows that are raised in factories are feed cheap grains loaded with steroids. The meat from a grass feed cow is very rich in healthy fatty acids and other essential nutrients.
Wild river salmon is also a great way to get your protein as salmon raised in the salmon farms are mostly infected and sick. The feed that they receive is cheap and does not include the yielded amount of the derivable omega-3 fatty acids.
Organic chickens are also a great, tasty and nutritious treat and are high in EFA’s. chickens bought from the commercial brands are improperly raised in toxic conditions and also feed cheap grains and steroids which can toxify your body after consumption.
meat is a valuable food because it is so dense in protein and nutritious fats. Sadly the meat farms and factories of today all but wipe out the nutritious value of the meat and leaves us with carcinogenic, toxic, diseased chicken wings and patties.
yoghurt is rich, fatty and very nutritious and low in sugar. Stay away from the 2 percent, low fat, and even no fat announcements as this foods are high in hormones, chemicals, refined sugars (even high fructose corn syrup) and bad fats.
Tuna fish is also a rich source of protein and very high in amino acids just make sure that you don’t eat that canned tuna (if that’s what it really is) stick to fresh fish markets as they get it straight from the source.
Eggs are rich in protein and high in antioxidants, vitamins and good fats just make sure that they are the organic kind as the nutritious value of commercial brand eggs in next to nothing. make sure to eat only the yoghurt made from raw milk as yoghurt made from processed milk is loaded with dangerous toxins.
When adding nuts to your diet go for almonds to get your protein and almond butter is way less toxic than commercial peanut butter.
All said and done its all about the quality of protein and not really the size of the protein as a giant stake will surely give you more protein if that cow was raised incorrectly and feed toxic hormones than you will be doing your body more harm than good.
